I've committed a fixed up version of the patch to natty. I can't reproduce the original problem on my hardware so cannot test it, but I think it's correct.
This adds an xorg.conf option ResolutionDetect, which is turned on by default. You can set it off in order to work around this bug.
I also added it as an xinput property so you should be able to flip it on or off using the usual xinput syntax.
